Application filed July 2, 1920. Serial No. 393,611.

new anduseful Improvements'in Operating- Ap'pliances for AngleCocks' forAir-Hose; and I dohereby declare the following to be a full, clear,andexact description of one form of my invention, reference being had tothe accompanying drawing, forming a part of this specification;

This invention relates to mechanism for operating the'valve in the'airbrake hose on the end of cars of. various kinds, which is devicerhas itsplug or valve turned by a lever that is pivoted thereon, and is normallyheld against a stop that would prevent turning ofthe valve by the lever,but when the lever is swung up 'the'p'lug can be turned by the lever.

The object of the present invention is to provide means for turning theangle cock from the top or upper part of the car.

A further object of the invention is to provide such operating meansthat will first swing the lever on the cock, and then turn the lever toopen or close the valve.

In the accompanying drawing showlng one embodiment of my invention,Figure 1 shows the end portion of a car with the angle cock, and theoperating means.

"Fig. 2' is a partial sectional view looking downward, taken above theslotted guide.

Fig. 3 is a similar view with the valve shifted.

Fig. 4 shows the upper guide for the operating rod.

Fig. 5 shows the slotted guide.

Fig. 6 shows the angle cock.

As set forth in the drawing, the car has the end denoted by 1, and theusual form of angle cock 2 is shown on the end sill of the car. Thisangle cock has a plug or key 3, with a lever 41: pivoted to the plug at5, to turn the plug and open or close the valve. This lever is providedwith an eye 6 for engagement with an operating member, extending to thetop of the car. A stop 15 on the lever engages a lug 16 on the anglecock and prevents turning of the plug 3, until the lever is swungupward. k

I provide means for swinging this lever to release it from the lug, andfor also causing the lever to turn the plug of the cock,

which means are operable from the top; of the car. I show an operatingrod 7 having a handle 8 at its upper end, adjacent the top ofthecar.This operating rod is shown supported in an eye bolt 9, secured to thecar end, and a collar 10 is shown clamped on the rod'to limit thedownward movement.

The lower end of the rod 7 has a suitable connection with the lever 4,preferably by having a spring hook 11 whereby it can detachably engagethe eye 6 of the-lever;

' It will be readily understood that a train-. man on top of the car cangrasp the handle Sof theoperating rod, andby drawing upward on thisrodwill swing the lever 4 upwardly, toreleaseit from'the locking lugs.

Thereupon'the handle 8 andfrod are given a twist, which will causethelever to swing to one side, and turn the plu'g of the angle,

cock.

I also provide a special guide member for the operating rod that willcause the rod at the lower portion to move rearward at a slight angle,of about thirty degrees to the side of the car, which is the angle atwhich the lever of the angle cock is normally positioned. The rod 7 willat its lower portion move back at this angle, and then as the lever andcock is swung itwill move toward the side of the car, at a right angleto its former direction of movement. I provide a special guide, shown inthe form of'a threaded stem 12 having slotted arms 13 and 14, see Fi 5.This guide is bolted to the car end 1', wit

the operating rod 7 extending through the slotted arm- The arm 13extends forward at an angle of about one hundred and twenty degrees tothe stem 12, and the slotted arm 14 extends toward the side of the carat a right angle to the other arm, with the slots connecting as shown.This guide is at tached to the car with the rod 7 in its normal positionlocated at the outer end of the slotted arm 13.

In the operation of this device, the rod 7 is first raised by the handlewhich will swing the lever 4: upwardly and release it from the lug 16,and the rod 7 will move back in the slot 13, when the rod 7 can beturned to swing the plug and the rod will then move through the slot 14of the guide. When released the rod 7 will move downward and the leverat will swing downward. To turn 7 then released which will returnltheseveral parts to their former position.

It is to be understood that various changes can be made by those skilledin this art, within the purview of the claims, without departing fromthe spirit and scope of my in-' vention.

What I claim is 1 d 1. The combination with a car provided with an airhose havingan angle cock with a hinged plug lever of an uprightoperating rod movably mounted 'on the car end, said 1 rod having amovable connection with said rod movably mounted on the car end, saidrod having a movable connection with said lever and'extending to the cartop, said rod being supported on the car to turn and also to be raised,whereby the operating rod can 7 be movedupward to raise the saidleverand thereupon turned axially to cause said lever to swing the anglecock plug, and a slotted guide on the car end engaging the operating rodplug.

3. The combination with a car provided with an air hose having an anglecock with a hinged plug lever, of an'u'pright operating rod movablysupported on the car end, said rod having a movable connection with saidlever and-extending to the car top, said rod being supported on the carto turn and also to be raised, wherebyuthe operatingrod can be movedupward to raise the said lever and thereupon turned axially to causesaid lever to swing the angle cock plug, and a guide on the ear endhaving an angular slot engagingthe operating rod to guide the rod toshift in two directions, whereby the saidrod will first move rearward inthe slot to.

raise the lever, and thereupon move laterally in the slot on turning ofthe angle oock plug.

4;. The combination with a car provided with an air hose and an anglecock at the car end connection, of an uprightoperating rod movablysupported on the car end and extending to the car top, said rod beingiconnected with the angle cock plug wherebythe' operating rodcan beswung lnto position to turn the angle cock plug.
